Rumours claim Jose Mourinho has been involved in bust-ups with several first-team players including Alexis Sanchez, Paul Pogba,, Anthony Martial and even Antonio Valencia.

Manchester United’s results haven’t been good of late, as United haven’t won a game in the last four matches. The 3-1 loss to West Ham last week lowered morale, and fans booed when United could only get a draw against Valencia in the Champions League on Tuesday night.

Some top players have been accused of not giving their all, and United legend Roy Keane has now sent a message to Pogba and Sanchez, urging them to put aside their frustration with the manager and play for the club if they aren’t willing to play for the manager.

“We talk about footballers and managers, not every player is going to get along with their manager and the manager is not going to like every player,” Keane told Notts TV.

“But what you do as a footballer, and whatever disagreements I’ve had with one or two managers, when you cross that line, you play for the team.

“I don’t care what fallout you’ve had with your manager, I don’t care if you’ve been at each others’ throats, because that is part of the industry, people do fall out, it happens in other industries.

“Unfortunately when you’re at Man United, one of the biggest clubs in the world, things will get exaggerated.

“But if you’re a footballer for Man United and you put that jersey on and walk out and don’t give 100 percent because you might be upset with somebody, then good luck to Mourinho in this job.

“Players who get upset with the manager or coaching staff and think ‘I’m not going to train properly because somebody upset me’… there’s a lot of cry babies out there.”

Manchester United now have the opportunity to bounce back with a victory in this weekend’s clash against Newcastle.
